backfire?
 

my car seems to have a small backfire everytime i change gear!!!! iv'e changed the plugs recently so i can't be them,any ideas???

cheers guys! :D

non-standard VTA dump valve? ;)

ahhh really? mine was fitted by the previous owner and does get on my tits now and again! will it cause any problems/damage?

cheers dude! :cool:

Can do - if you still have any cats fitted it is possible for a large backfire to damage them.

iv'e got a full de-cat which would explain why the tailpipe is constantly black! :rolleyes:

why does this happen? is it to do with overfueling,i'monly getting about 120 miles to a tank full? :(

cheers mate! :thumb:

Your exhaust is always going to get black and dirty, whether yours is getting filthy quickly is hard to tell on here.

120 miles from a tank is bloody low though. If you've still got your std dv then put it back on and see what happens.

unfortunatly i dont have the standard DV! (oh crap) :(
